Serial No. 552,311.

To all 'whom it mayconcem:

Be it known that I, FRANK SCHORIK, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Coin-Detectors, ofF which the following is a specification.

My invention relates to improvements in coin detectors and has for its object the production of a coin detector which shall be simple of construction and efficient in operation.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a perspective view of a piano provided with a coin detector embodying my invention, Fig. 2, an enlarged front elevation` of the detector, Fig. 3, a side elevation of the detector, Fig. 4, a rear elevation of the detector, Fig. 5, a section on line m-' ofv Fig. 7, Fig. 6, a section on line y-y of Fig. 7, Fig. 7, a section on line .e-a of Fig. 6, Fig. 8, a detail section of the operating memberof the. device, Fig. 9, a perspective view of the retaining pawl employed in the device, and Fig. 10, a perspective view of the locking dog employed in the device.

The preferred form of construction as illustrated in the drawings comprises a suitable boX or-casing 1 provided with a suitable cover plate` 1. At its upper forward portion the cover 1 is provided with a boss 2 having a recess therein. adapted to receive the coin .destinedtooperate the machine, in this case a five cent piece or nickel. The recess in boss 2 leads to a coin. receiving chute 3. Below chute 3 the cover 1 is `provided with a boss 4 in whichv a. shaft 5 is rotatably mounted. At its outer end shaft 5carries an operatinghandle 6 and at its inner end a plate 7 secured thereto by means of .a hub 8` and pin 9. The plate7 is provided` with a coin chute 10 registering with receiving chute 3 when said memberis in normal position and adapted,` to cont-ain a nickel or similar object 11. A spring 12 secured. to a stationary llug 13 anda screw 14 on member 7 serves to yieldinglyhold the member 7 in normal| positionv with, the projection 15 thereon, contacting with the stationary stop 16. A .retainingpawl 17 is pivoted to member 7 at 18 and is provided with a surface 19 adapted to coperate with the side 20 of chute 10 to retain a deposited coin in said chute. A spring 21 serves to normally hold the pawl 17 in its operative position and a set screw 22 adapted to contact with a shoulder 23 on member 7 serves to nicely regulate the distance between surface 19 and side 20, so that a nickel will be retained in said coin chute but a coin of very slightly smaller diameter will pass therethrough.

In its upper portion member 7 is provided with a notch 24 adapted to receive a locking dog 25 pivoted to a stationary support by a pivoted screw 26. The dog 25 is provided with an inward projection 27 adapted to enter the upper portion of slot 24 and having a locking surface 28 adapted to coperate with the side 29 of slot 24 to lock member 7 against rotation. The end 30 of projection 27 is beveled as shown and pawl 25 is provided with a pin 31 projecting into notch 24 to contact with a nickel 11 retained in coin chute 10. The relative arrangement is such that when pin 31 contacts with the coin, as shown in Fig. 8, the surface 30 is raised to a position where` it is ada ted to ride upon the edge of locking surface 29 upon operative rotation of member 7 to force dog 25 out of notch 24,. an inclined land 32 being provided on member 7 to continue this outward movement of dog 25 during further rotation of member 7. A spring 33 secured. to stationary projection 34 and to lug 35 on Vdog 25 serves to yieldingly hold said dog in engagement with notch 24, the arrangement being such that when plate 7 is in normal position the side of projection 27 opposite to locking surface 28 rests upon the side of notch 24 opposite to locking side 29 to hold pin 31 from obstructing coin chute 10. By this constructiom'it will be observed that, upon deposit of a nickel in coin chute 10, the member 7 is rendered free to rotate since the pin 31 rides upon the nickel 11 until inclined surface 30 strikes the edge of locking surface 29, whereupon' Y dog 25 is operated to permit further rotalatter is in normal position so that if a coin or slug, smaller in diameter than a nickel, is deposited in coin chute 10 it will pass through said chute into delivery chute 36 whence it will pass to a delivery receptacle 37 to which chute 36 leads. Delivery receptacle 37 is provided with an outwardly extending lug 37 adapted to contact with the upper edge of a slug or coin and cause the same to tilt outwardly which facilitates removal. A guard 3S is pivoted to swing across chute 36 and into a recess 39 in the wall thereof and serves to preventinsertion of a wire or other similar thing into chute 36. By this construction it will be observed that a coin of less diameter than a nickel will pass freely through the device and be delivered to the depositor in receptacle 37. A coin larger than a nickel cannot be inserted in boss 2 so that only a true nickel or a slug of exactly the same size as a nickel can be utilized to operate the device.

In order to insure that any true nickel deposited in the device will properly operate the same, I provide on plate 7 an upwardly extending stop member 40 adapted to traverse chute 3 on operative movement of plate 7 and intercept any coin or slug deposited in chute 3 during the operative movement of plate 7. The rearward side 4l of projection 40 is inclined as shown, so that upon the inoperative movement of plate 7 a retained coin or slug in chute 3 will be automatically elevated to pass over said stop and pass into coin chute l0 where it will operate as before.

A retaining chute 42 is arranged on cover l in position to register with coin chute 10 at the end of the operative movement of plate 7 and pawl 17 projects from member 7 suiiiciently to contact with stop 16 to cause release of a coin retained in the coin chute 10 at the end of the operative movement of member 7. Thus a coin retained in chute l0 will be automatically discharged into chute 42 upon the operative movement of plate 7. The passage of a coin through chute 42 is obstructed by a pin 43 carried by a pivoted arm 44 and projecting through a slot in a wall of said chute. Arm 44 is held in operative position by means of a spring 45. A glass or other transparent plate 46 is set in the wall of chute 42 so as to render a coin retained by pin 43 visible from the outside. Plate 7 carries a projection 47 having an inclined cam surface 4S adapted to contact with a coin resting on top of the coin retained by pin 43, so that upon the reverse movement of plate 7 cam surface 48 will operate against a coin supported on top of the visible coin to cause the discharge of the latter. Thus it will be observed that the first coin deposited will be retained by pin 43 in a position for inspection until a coin is visible on top thereof by the next operative `ing from the spirit of the invention.

movement of said plate whereupon the rst coin will be dislodged and the new coin immediately placed in visible position for inspection. This provision will tend to discourage operation of the machine by slugs or spurious coins. Chute 42 leads to another chute 49 located within a piano or other instrument and arranged to conduct the coin to automatically operating mechanism therefor (not shown). By this arrangement it will be observed that a true nickel of correct size will be retained in the detector and delivered to chute 49, thus serving to operate the instrument as will be readily understood by those skilled in the art.

At the bottom of cover plate 1 is provided a lug 50 carrying a downwardly extending pin 51 arranged to project into a perforation provided in the bottom of casing l. At its top plate 1 carries a lock 50 secured to form the back of the recess in the boss 2 and arranged with its key-hole accessible through said recess. The bolt 53 of said lock is arranged to engage a lug 54 on casing l to lock cover plate l in position. It will be observed that all of the operative parts are carried by cover plate 1 which may be readily removed from the casing for inspection or repair.

While I have illustrated and described the preferred form of construction for carrying my invention into effect this is capable of variation and modification without depart- L therefore, do not wish to be limited to the exact details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
